Truck-Lite 44248Y – Super 44, 4" Round Yellow In-Phase LED Rear Turn Strobe Light (6 Diode, Turn Signal Override, Class II, Hardwired Stripped End, 12V)
Maximize rear hazard visibility and turning safety with the Truck-Lite 44248Y Super 44 In-Phase LED Strobe Light. Designed for commercial trucks, highway service vehicles, utility fleets, and emergency equipment, this 4-inch round yellow warning lamp features 6 high-output LEDs with an integrated Turn Signal Override function. Configured as an In-Phase unit, this ultra-slim, hardwired lamp produces synchronized quad-flash patterns when paired with another In-Phase unit (or an alternating lateral flash when paired with an Out-Phase companion like the 44249Y)—all without requiring expensive external flasher control modules.
The Truck-Lite 44248Y Super 44 In-Phase Rear Turn Strobe Lamp provides high-conspicuity warning capabilities while preserving full turn signal functions. Utilizing Truck-Lite's signature 6-diode optical layout, it offers a clean, uniform aesthetic that seamlessly matches standard Stop/Tail/Turn and Back-Up lamps on commercial truck bodies. When installed in tandem with another In-Phase unit (or paired with an Out-Phase unit like the 44249Y), it delivers synchronized or alternating quad-flash patterns directly through its self-contained internal circuitry—saving on hardware costs and installation time.
Safety is paramount when working alongside active roadways and highway traffic. The 44248Y features an internal turn signal override feature that automatically pauses the quad-flash strobe pattern whenever the vehicle's turn signal is engaged, ensuring surrounding drivers clearly see your directional indication. Once the turn signal cancels, the lamp instantly resumes its strobe warning function.
Featuring an ultra-compact depth under 1 inch, the 44248Y easily mounts in space-restricted grommet cutouts on vehicle rear panels. The solid-state LEDs and internal electronics are completely encapsulated in an impact-resistant ABS housing with an acrylic lens, shielding components against water immersion, severe vibration, road chemicals, and salt spray. Built with a hardwired 4-wire lead terminating in stripped blunt-cut ends, this strobe light allows versatile hardwire splice connection into any 12V electrical system.
